METHOD oF MAKING BUTTONS.

SPECIFICATION forming part of Letters Patent No. 384,226, dated June 5, 1888.

Application filed December 9, 1887. Serial No. 257,335. (No model.)

T0 @ZZ whom it'mcty concern.:

Be it known that I, SHUBAEL GoT'rLE, of the city, county, and State of New York, have invented a new and useful Process for the Manufacture of Stud, Collar.,or Sleeve Buttons, of which the following is a speciticatiou.

My invention consists in a new process of manufacturing a stud, collar or sleeve button from a single piece of metal, the said button consisting of two flanged portions united by a hollow shank or post, one of said flanged portions being of solid metal.

In the aceolnpanying drawings, Figures 1 to 5, inclusive, are sectional views of my button during different successive stages of its manufacture. Figs. 6 to 8, inclusive, exhibit the successive stages of a button made by a modification of my process. In the process illustrated by Figs. l to 5 the solid portion of the button is flat-tened and drawn out to form a solid base or back. In Figs. 6 to 8 this por tion of the button is rounded or otherwise suitably shaped to produce a head.

Similar lettersv of reference indicate like parts.

I Iirst produce a tube of metal, A, having at one end a solid portion, B, as shown in Fig. 1. I next draw said tube into the shape shown in Fig. 2. The solid part B is then liattened or drawn out to produce the solid back B, as shown in Fig. 3. This I may do by upsetting. The button is next adj usted in the lathe, so that the open end A, Fig. 3, is conveniently presented to the action of' a spinningtool,.and by means of this tool the eireumfer eutial edge is spun inward, as shown at A', Fig. 4. This spinning operation is continued until the opening is entirely closed by the metal meeting, when the upper surface of the lhead A', Fig. 5, is finally smoothed off, thus completing the construction of the button,

which, as shown in the last-mentioned figure,

has a solid back and a hollow shank and hollow head. i

I may equally well from the form of blank shown in Fig. 2 produce a button having a solid head in lieu of a solid back. The metal at the circumferential edge of the opening is approximated, as shown at a in Fig. 6, and linally brought into contact, so closing the aperturc, as indicated at a', Fig. 7. The hollow portion of the button thus closed is nally iiattened to produce the back or base a, Fig. 8, and the solid end, if desired, is flattened and rounded, as shown at b.

In another application for Letters Patent, filed November 2l, 1887, Serial No. 255,708, and now pending, I have fully described and claimed the construction of a stud, collar, or sleeve button, having a hollow post and shank and solid back and formed from a single piece of thin metal without opening into its interior. The subject-matter of said application is therefore herein diselaimed.

I claiml. The process of manufacture from a single piece of metal of a stud, collar, or sleeve button having two llanged portions united by a hollow shank or post, one of said flanged portions being hollow and the other solid, Awhich consists in first producing a tube of thin metal, A, having at one end a solid o114 thickened portion, B; second, compressing and so reducing the diameter of said tube adjacent to said thickened portion B, as at C, and, third, closing the open end of said tube by pressing into-close contact the metal around the edge of the opening in said tube, substantially as described.

2. The process of manufacture from a single piece of metal of a stud, collar, or sleeve button having a hollow head, a hollow shank, and a solid back or base, which consistsin first producing a tube of thin metal, A, having at one end a solid or thickened portion, B; second, compressing and so reducing the diameter of said tube adjacent to said thickened portion B, as at O; third, drawing out or flattening said solid or thickened portion B, as at B', and, fourth, closing the open end of said tube by pressing into close contact the metal around the edge of the opening in said tube, substantially as described.

3. The process of manufacture from a single piece of metal of a stud, collar, or sleeve button having a back and shank of thin metal and a solid head, which consists in Iirst producing a tube of thin metal, A, having at one end a solid or thickened portion, B; second,`

compressing and so reducing the diameter of said tube adjacent to said thickened portion, as at C; third, closing the open end of said tube by pressing into close contact the metal around the edge of the opening in said tube, as at c', and,4fourth, flattening the portion so closed, as at a, substantially as described.
